Pulmonary fibrosis is a result of repeated injury to areas of the lung. This causes inflammation and excess connective tissue to develop. It is often described as scaring of the lung. The scar can prevent the lung functioning properly, therefore it can lead to breathing difficulties.
Stem cells have the potential to self-generate themselves into many different cell types in the body. Autologus stem cell therapy is when the patients own stem cells are used to treat the condition. Bone marrow or peripheral blood stem cells are collected from the patient and then frozen and stored until they are needed. Alternatively, the stem cells originate from a donor, this is the allongenic approach.
The stem cells are then implanted into the patient so they can self-generate, replace the cells that have been damaged and repair the scar tissue in the lungs.
